The seal of the stud coupling is specified by what is laid down in ISO standard 6149-80 and DIN standard 3482. To obtain the correct assembly on all terminal fittings it is essential to adhere to the tightening torques shown in the following table: Thread Tightening Torque (Nm) ± 10 M10 x 1 22 M12 x 1.5 24 M14 x 1.5 30 M16 x 1.5 35 M18 x 1.5 36 M22 x1.5 40 M26 x 1.5 45 The tubing must be cut at the right angles with a maximum tolerance of 15°. Correct assembly is performed only when the tubing is inserted touches the end of the tube seat. To be absolutely certain that this is the case it is advisable to mark the depth of the tubing coupling (distance H).

To make the operation easier it is sufficient to slightly turn the tubing. The force required for the fitting is shown in the following table. Screw the swivel Coupling into the thread ensuring the correct torque (Over-tightening can cause damage to both the fitting and the component). The fit the component by means of push and twist . IMPORTANT: Check the component is coupled correctly and securely. Pull the component to ensure The Dimensions shown in the tables in the catalogue are only shown as a guide.
